My car went for the last time for services and I have a couple things want fixed. So I flash back to stock including transmission flash.

Once I got back my car I immediately flash bm3 s1 including the transmission flash BUT now they is this weird transmission feeling shifting up during WOT above 6k rpm shift. I can't describe it... the best I can describe it is double thud sound. This was not happening before.
